The biggest concern is with veteran defensive tackle Raheem Brock, who hurt his left hand in Friday's loss to the Vikings and had a cast on his left arm as he sat out the team's light workout on Saturday.

Defensive end Robert Mathis also missed Saturday's workout.

Mathis left Friday's game early after suffering a bruise.

Caldwell met with the media briefly on Saturday and said that he did not know how long Brock will be out.

He hopes to know more about the status of both Brock and Mathis today.
